“…It also allows the comparison among Fanger's model (through PMV and PPD), adaptive model and other less-common thermal models. Several studies investigated the accuracy of EnergyPlus (EP) results in fields such as energy consumption [67,68], energy retrofitting [69,70], thermal resiliency [71,72] and, of course, thermal comfort [73,74]. Major contributions are summarised in Table 3.…”

This paper presents a review of technologies under the paradigm 4.0 applied to the study of the thermal comfort and, implicitly, energy efficiency. The research is based on the analysis of the Internet of Things (IoT) literature, presenting a comparison among several approaches adopted. The central objective of the research is to outline the path that has been taken throughout the last decade towards a people-centric approach, discussing how users switched from being passive receivers of IoT services to being an active part of it. Basing on existing studies, authors performed what was a necessary and unprecedented grouping of the IoT applications to the thermal comfort into three categories: the thermal comfort studies with IoT hardware, in which the approach focuses on physical devices, the mimicking of IoT sensors and comfort using Building Simulation Models, based on the dynamic modelling of the thermal comfort through IoT systems, and Crowdsensing, a new concept in which people can express their sensation proactively using IoT devices. Analysing the trends of the three categories, the results showed that Crowdsensing has a promising future in the investigation through the IoT, although some technical steps forward are needed to achieve a satisfactory application to the thermal comfort matter.

The thermal comfort conditions of the educational buildings affect students' attention, focus, perception and learning levels. The design of transparent areas is important in the control of solar radiation affecting thermal comfort conditions. The aim of this study is to determine thermal comfort conditions in classrooms with different transparency ratios and to make suggestions for improvements. Classrooms in the same building on the university campus, in the same direction (south) and with different transparency ratios were determined as study areas. Measurements (PMV-PPD) and surveys (AMV-APD) were carried out during a day in heating period. The thermal comfort conditions were evaluated according to the comfort intervals specified in ASHRAE-55 and ISO-7730 standards. The results showed that there were significant differences in thermal comfort between classrooms. If the transparency ratio is more than necessary, it causes discomfort and redundant energy consumption. Suggestions have been made to ensure solar control and thermal comfort conditions.

“…In addition to occupants' behavioral preference, a study on window design in architecture showed horizontal windows produce higher energy-saving than any other type in the northern facades in London, the UK [46]. In a study on the westand east-facing rooms, continuous horizontal windows performed better than other types of windows and separate windows with the same glazing ratio in a temperate-dry climate [47]. Similar studies show the benefit of windows that are stretched horizontally [48].…”

This study aims to determine the optimum size of windows based on the window-to-floor ratio (WFR) for the main cardinal directions in Hot-summer Mediterranean (Csa) and Dry Summer Continental (Dsa) climates (Köppen–Geiger classification system) by carrying out a multi-objective optimization that relies on three dynamic metrics of Useful Daylight Illuminance (UDI-a (autonomous)), Daylight Autonomy (DA), and Annual Sunlight Exposure (ASE1000,250) in Radiance version 5.1. A validation against field measurements is conducted under an overcast sky with an illuminance of 11000 lux. The Pareto front is used to pick the best solutions for evaluating the most optimized solutions. Accordingly, the minimum standards for cardinal directions in each climate are defined. The minimum suggested WFR for the Dsa and Csa climates for the south-, east-, north-, and west-facing windows are 20%, 15%, 20%, and 15% (Dsa) and 20%, 20%, 25%, and 20% (Csa), respectively. Furthermore, the results show the shape and relative proportions of windows (vertical/horizontal) have a significant effect on the metrics. As a result, this paper introduces the “Proportion Ratio” as a new indicator for designing windows.
